New Resin commands to manage JMX objects
Resin 4.0.18 introduces new commands to help manage JMX objects. These commands also eliminate the need to run a JMX console.
New commands include:
- jmx-list – listing JMX MBeans, attributes, and operations
- jmx-set – setting attribute value on MBeans
- jmx-call – invoking method on a MBean
Starting with version 4.0.17, administrators and programmers can now perform debugging and monitoring of tasks on remote Resin server using Resin’s extended set of command lines. Resin users should be familiar with thread dumps, profile, and heap capabilities to effectively use the Resin command lines. Make sure to enable the commands by registering ManagerService in resin.xml file before you start.
Resin Cloud Computing Support – bringing elastic cloud to Java EE developers
What should a Java EE developer expect from a cloud solution and what makes it good? Here are four criteria you should consider when researching a Java EE application server provider with a cloud offering.
Criteria defining Cloud solutions:
- Cloud ready
- Elastic ready
- Node management in the cloud
- Version management in the cloud
Resin’s cloud support means having an intelligent load balancer, a reliable cloud coordinator, a fully cloud aware deployment and versioning mechanism. Resin application server allows for management of an entire pod of nodes from load balancer to http proxy cache to pod coordinator to individual servers within a single admin tool. Resin goes beyond just being a processor node in an elastic cloud. It is truly and intelligent elastic cloud coordinator bringing the promise of cloud computing into the hands of Java EE developers.

JavaOne will be held at the Hilton Hotel on October 2-6 and will be co-located with Oracle World. Caucho® will be exhibiting at booth 5409. This will be a great week to meet and share Caucho’s latest developments with Resin and the Web Profile. Contact us at firstname.lastname@example.org if you will be near the Bay Area or plan to attend JavaOne to arrange for a meeting.
Overview of Resin directory structure and installation
New and old users alike can benefit from a clearer understanding of Resin’s directory structure and contents. In this tech tip, each important directory is described, followed by examples of typical installation parameters and the effect on directory locations.
Four main Resin directories and default location includes:
- Resin Home – default location: /usr/local/resin
- Resin Root – default location: /var/www
- Resin Config – default location: /etc/resin
- Resin Log – default location: /var/log/resin
Alternatively, Resin can be installed in a single directory. This is the recommended method for getting started, especially for those who prefer to keep installation simple or don’t have root access. And this is how it’s done:
- unzip resin-pro-4.0.18.zip
- cd resin-pro-4.0.18
- ./configure –prefix=’pwd’
- make install
